Description and Introduction

ASK/FSK 434MHz Wireless Transceiver The TDA5255E1 is a FSK/ASK transceiver IC manufactured by Infineon Technologies. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:  

### **Specifications:**  
- **Frequency Range:** 433 MHz (ISM band)  
- **Modulation:** FSK (Frequency Shift Keying) and ASK (Amplitude Shift Keying)  
- **Supply Voltage:** 2.1 V to 5.5 V  
- **Current Consumption:**  
  - Low-power mode: < 1 µA  
  - Standby mode: ~ 10 µA  
  - Active mode (RX): ~ 10 mA  
  - Active mode (TX): ~ 25 mA (at 10 dBm output power)  
- **Output Power:** Adjustable up to +10 dBm  
- **Sensitivity:** -110 dBm (for FSK, 1.2 kbps)  
- **Data Rate:** Up to 64 kbps  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** P-TSSOP-28  

### **Descriptions:**  
The TDA5255E1 is a highly integrated, low-power RF transceiver designed for short-range wireless communication in the 433 MHz ISM band. It supports both FSK and ASK modulation schemes, making it suitable for applications like remote keyless entry (RKE), home automation, and industrial telemetry.  

### **Features:**  
- **Low Power Consumption:** Optimized for battery-operated devices.  
- **Integrated PLL & VCO:** No external components needed for frequency synthesis.  
- **On-Chip Data Filtering:** Reduces external component count.  
- **Configurable Output Power:** Adjustable via software.  
- **Wake-on-Radio (WOR) Support:** Enables ultra-low-power listening modes.  
- **SPI Interface:** For digital control and configuration.  
- **Built-in RSSI (Received Signal Strength Indicator):** Helps in signal strength monitoring.  

This information is based solely on the manufacturer's datasheet and technical documentation.
